|Mitch||Alessandro Beagle in new GP Magazine|
Has anybody seen the review in the new GP of the Alessandro Beagle amp? It has pictures of the inside of the chassis with the article. Looks like a 6SL7 preamp with a Fender type tone stack right after the first stage. A second 6SL7 is used for the LTP-PI to drive a pair of UL, cathode-biased Sovtek EL84's in Class A at 240V. The article says the output tubes for all the Alessandro amps are run in UL. The pictures are color so I was hoping to make out some of the values used on the resistors. It looks to me like 220k plate loads on the 1st 6SL7 and a 470 bias resistor on the PI. All the caps in the PI (except the input cap) are paper-in-oil and look to be the same size; I would guess 0.1 microfarad. The PI input cap and two of the caps in the tone stack look to be orange drops; they look like the 0.02 microfarad size and shape to me. I would love to hear your opinions on what all the values for the resistors and caps might be for this supposedly great sounding amplifier, as I was thinking of building something very similar but with 6V6 output tubes instead of the EL84's. Thanks.
